Following Discarded Science: Ideas That Seemed Good at the Time, and Corrupted Science: Fraud, Ideology, and Politics in Science, Hugo Award winner John Grant here looks at pseudoscience, the studies that sound almost scientific, or seem like they might make sense, but are in fact grounded in superstition, paranoia, or wishful thinking.

"Grant's book ranges widely, from ancient and modern geocentrists and flat-earthers to inventors of perpetual motion machines, promoters of zero point energy, discoverers of Atlantis ... and hunters of Bigfoot ... taking in a lot more along the way. There's something very satisfying in seeing that every design for a perpetual motion machine (weights! magnets! no, wait, water ...) that I ever scribbled on the back of a physics jotter in high school was anticipated centuries earlier by people much cleverer than myself.... Beautifully produced, endlessly entertaining and highly recommended."—Ken MacLeod
